Kendon White Oil Insecticide 20L – Bulk Petroleum Spray Oil for Scale, Aphids & Mites

Kendon White Oil Insecticide 20L: Bulk Petroleum Spray Oil for Scale, Aphids and Mites

Kendon White Oil Insecticide in the 20L drum is the bulk, commercial-size petroleum spray oil for larger-scale pest control across orchards, groves, large gardens and ongoing spraying programs. It contains 825g/L petroleum oil and works physically rather than chemically, coating pests in a fine film of oil that blocks their breathing pores and suffocates them. Kendon is an Australian-owned company that has been manufacturing white oil since 1950, and this large drum is aimed at growers, commercial operators and anyone who gets through a lot of oil across the season.

Because it kills by smothering rather than by a chemical toxin, white oil handles the soft-bodied and armoured pests that are hard to control otherwise, including scale, aphids, mites, mealybugs and citrus leaf miner. It is particularly valued for the hard, waxy scale insects on citrus and fruit trees that resist many other sprays. It also carries a low poison profile, a Schedule 0 (unscheduled) product with a one-day withholding period, so treated edible crops can be harvested soon after spraying.

At 20 litres, this is the most economical way to buy white oil for anyone managing multiple trees, a commercial planting or a large property, giving you plenty of concentrate to dilute and spray throughout the year.

How to Use

White oil is a concentrate that you dilute with water and spray, and the correct dilution rate varies by pest and plant, so always mix according to the rate on the product label for your situation. Mix thoroughly, then spray to thoroughly wet the plant, covering both sides of the leaves, stems and the undersides where scale and mites hide, until just before run-off. Because it works by contact and smothering, complete coverage of the pest is essential, and a repeat application is often needed to catch newly hatched pests. For larger jobs, mix only as much diluted spray as you will use, and agitate the tank to keep the oil evenly dispersed.

Timing matters with oils. Spray in the cool of the early morning or evening, and avoid spraying in hot weather (generally over about 30°C) or on drought-stressed plants, as oil applied in heat can burn foliage. Do not spray oil-sensitive plants, and test a small area first if unsure.

Safety and Responsible Use

• Read and follow the label. Mix at the labelled rate for your pest and plant, and observe the one-day withholding period on edible plants.

• Avoid heat and stress. Don't spray in hot conditions or on stressed plants, to prevent leaf burn.

• Check plant sensitivity. Some plants can be damaged by oil, and white oil can strip the blue bloom from some conifers.

• Protect yourself. Avoid contact with skin and eyes, wear suitable protection, and wash your hands after use.

• Dangerous goods shipping. As a petroleum product this drum ships by courier, may travel on a pallet, and can't go to a PO box.

Frequently Asked Questions

What is the mixing ratio for Kendon White Oil?
White oil is diluted with water, but the correct rate depends on the pest and plant, so follow the dilution table on the product label rather than a single fixed ratio. Mix thoroughly and spray to full coverage.

Is the 20L better value than smaller sizes?
Yes. The 20L drum is the bulk size and works out cheaper per litre, which suits orchards, commercial growers and large properties that use a lot of oil across the season.

What pests and plants is it for?
It controls scale, aphids, mites, mealybugs and citrus leaf miner on citrus, deciduous fruit trees, roses, ornamentals, daphne and indoor plants, among other listed crops. Avoid oil-sensitive plants.

Can I spray it on fruit before harvest?
It has a one-day withholding period, so edible plants should not be picked for one day after spraying. Otherwise it can be used close to harvest.

When is the best time to spray?
In the cool of the morning or evening, avoiding hot weather (over about 30°C) and drought-stressed plants, since oil in heat can burn foliage.
